Windows Terminal version

1.12.10982.0

Windows build number

10.0.19044.1706

Other Software

java

Steps to reproduce

wt new-tab --focus --title "Test App 1.0.0" -d "C:\Users\jredfox\Documents\dev\OpenTerminal" -p "Command Prompt" cmd /c call "C:\Users\jredfox\AppData\Roaming\OpenTerminal\scripts\boot\boot.bat" "" "Test App 1.0.0" ",C:\Program Files\Java\jre1.8.0_333/bin/java, -Dot.l -cp ,C:\Users\jredfox\Documents\dev\OpenTerminal\bin, jml.ot.OTMain" "true"

the batch file

@ECHO OFF
IF NOT "%~1%" == "" (
   echo "%~1%"
   cls ::hotfix for Windows Terminal
)
title %~2%
set boot=%~3
set boot=%boot:,=^"% ::RE-MAP the boot command to double quotes
call %boot%
IF "%~4%" == "true" (
set /p DUMMY=Press ENTER to continue...
)
exit 0 ::Work around from a command prompt bug

It opens up like 20 tabs instead of one. with the ansi escape sequence in the batch variable string.

Expected Behavior

it opens up the my java program in wt with the colored output.

Actual Behavior

instead it opens up 20 tabs. it's having some wild behavior. switching to conhost.exe and cmd fixes the issue. I am going to work around this by changing the ansi escape to another character but this is just very silly
